2011-08-23bring back ___environ symbol (3 underscores)Rich Felker1-0/+1
its existence doesn't hurt anything, and dynamic-linked binaries using previous versions of musl were wrongly binding to it instead of __environ.
2011-08-23security hardening: ensure suid programs have valid stdin/out/errRich Felker3-13/+38
this behavior (opening fds 0-2 for a suid program) is explicitly allowed (but not required) by POSIX to protect badly-written suid programs from clobbering files they later open. this commit does add some cost in startup code, but the availability of auxv and the security flag will be useful elsewhere in the future. in particular auxv is needed for static-linked vdso support, which is still waiting to be committed (sorry nik!)
2011-07-28fix for setenv bogus var argument handlingRich Felker1-1/+1
thanks to mikachu per POSIX: The setenv() function shall fail if: [EINVAL] The name argument is a null pointer, points to an empty string, or points to a string containing an '=' character.
